is equivalent to .
When you add and you get .
reduces to and is equivalent to .
Example Question #224 : Grade 7
Evaluate:
The sum of two numbers of unlike sign is the difference of their absolute values, with the sign of the "dominant" number (the positive number here) affixed:
Subtract vertically by aligning the decimal points, making sure you append the 3.2 with a placeholder zero:
This is the correct choice.
Example Question #2 : How To Add Fractions
Evaluate:
Rewrite these numbers as improper fractions.
Now evaluate:
, so
Example Question #482 : Arithmetic
Add:
Rewrite using the lowest comon denominator. Since :
Example Question #483 : Arithmetic
When adding fractions, both denominators must be the same. A quick and easy way to do this is to multiply the numerator and the denominator of each fraction by the other fraction's denominator:
and
The is multiplied by 6 on both ends because the denominator of is 6. Likewise, is multiplied by 3 on both ends because the denominator of is 3. The problem should now look like this:
Remember to reduce. 15 and 18 are both divisible by 3.
Your answer is .
Example Question #3 : How To Add Fractions
Add the following fractions and simplify, if possible.
In order to add fractions with different denominators, first find a common denominator of the fractions by finding the least common multiple. The least common multiple of these denominators is:
and .
Because already has the required denominator, nothing needs to be done to .
Since the in needs to be multiplied by in order to get as the deonominator, multiply the numberator of by .
The "new" addition problem is now: .
The answer to this question is therefore .
Because and do not have a common factor, the answer cannot be simplified.
Example Question #5 : How To Add Fractions
To add two fractions, first find the common denominator. We can convert to . , which reduces to .
